Wilbur and Orville Wright
How They Invented the AirplaneBy Michael Aiken
May, 2005
Wilbur and Orville Wright-Wilbur Wright (shown on the left) was born on April 16, 1867 in Millville, Indiana-Orville Wright (shown on the right) was born on April 19, 1871 in Dayton, Ohio.
Wright Cycle Co.The brothers built bicycles and plane
parts here. Another thing they constructed was a
wind tunnel.
They also built many test wings out
of wax, iron, and steel at different
angles and sizes for test purpose.
Achieving Flight“We knew that men had by common consent adopted
human flight as the standard of impossibility. When a
man said,’It can’t be done, a man might as well learn to
fly,’ as he was understood as expressing the final limit of
impossibility.”Wilbur Wright

A machine that flies must have...
Kitty Hawk, North CarolinaThey needed a testing ground for their planes. The U.S. Weather Bureau recommended Kitty Hawk, North Carolina: A windy site with stretches of sandy beaches.
1900 Wright Glider
The 1900 Wright glider had a17 ft. wingspan and a light wooden frame covered with sateen. The brothers
would fly the gliders like kites. Since there is much wind, the lift causes the
plane to rise above the ground.
1901-1902
The 1901 glider crashed when it spun
out of control. In 1902, the brothers used a wind tunnel for testing wing and propeller design by
running air over each.
Angle of AttackAs the leading edge of the wing tilts up,
air moves faster over the top of the
wing, increasing lift, making wind rise.
Propellers
The brothers knew that they had to have a curved wing since the wing would
slice through the air. They also knew that the propellers would have to have
the right diameter, pitch, and area.
The Wright’s Propellers
There were two propellers on all the
Wright Fliers and they turned in opposite
directions to keep the plane stabilized. The
propellers were connected to the motor through a
sprocket-and-chain transmission, like the
kind used to pull a bicycle.
Now, they need an engine... The Wrights needed
an engine that produced at least 8
horsepower and weighed under 200
pounds. Luckily, they found an amazing
engine that exceeded both qualities.
The Wright Brother’s Engine
Their engine was state-of-the-art. It was made by Charlie Taylor. This engine produced 12 horsepower and only
weighed 179 pounds. It was considered remarkable and helped the Wright
Brothers achieve success.
1903 Wright FlierThe 1903 Wright Flier was a product of the tests that the brothers did in 1902. On their third try, Wilbur flew for 12 seconds. It was the first time anyone had been in flight.
Wing-WarpingWing-warping: to
adjust the position of
the wings to balance the plane after
turning
Ailerons
The 1903 Flier had ailerons. They were devices that helped control the
plane. Ailerons looked like flaps at
the ends of the wings that could control dives and
climbs.
1905 Wright FlierThe 1905 Wright Flier was tested in Huffman Prairie, Ohio. It’s longest flight was 39 minutes. It weighed over 700 pounds and was thought of as the “First Practical Airplane.
Biplane Blunders
The brothers biplanes tended to spin out of control. They fixed
this problem by adding ailerons. The Wright brothers also made the plane turn by installing a spiral twist running down
the wings.
Work Does Pay Off...After all the inventing,
the Wrights took a tour in Europe in
1906-1908, demonstrating their invention. In 1909,
they returned to America.
The Beginning of a LegacyWilbur died on May 30, 1912 from
typhoid fever at the age of 45. Orville died on January 27, 1948. All of their
planes that survived their purposes are currently inside the Smithsonian
Institution’s Air and Space Museum.
The Wright Brothers MemorialThe Wright Brothers Memorial was
constructed after the Wright Brothers had died. The Memorial is meant to
honor the Wrights for their remarkable achievements in flight.
